Product Characteristic

1、The large current generator has two ammeters,Size range monitoring.
2、The autotransformer can be adjusted freely.
3、status indicator lamp,press-button control,simplicity of operator.
4、Integral separable structure,easy to move on.

Product Function

1、High-Current Output: The system delivers a large, adjustable secondary (output) current, with models ranging from 500A up to 10,000A. The output is controlled by a free-adjustable autotransformer.
2、Dual Ammeter Monitoring: The unit features two ammeters for monitoring, allowing for size range monitoring of the output current for enhanced measurement accuracy and safety.
3、Flexible Structural Design: The device is available in either an integral structure (for smaller models) or a fission structure for larger models. This design improves portability, as the heavier components can be moved separately.
4、Simple and Safe Operation: Operation is controlled via status indicator lamps and press-buttons, making the process straightforward and easy to manage. It is designed for short-time or intermittent duty cycles.
5、Customizable Parameters: The product can be customized to meet special specifications beyond the standard parameters listed, offering flexibility for unique testing requirements.

Product Advantages

1、High Portability: The separable structure for larger models allows the heavy transformer and control elements to be separated for easier transport and on-site setup, overcoming the limitation of bulky, single-unit designs.
2、Precise Output Control: The freely adjustable autotransformer provides smooth and precise control of the output current, which is essential for accurate testing.
3、Enhanced Measurement and Safety: The inclusion of two ammeters provides a check on the output current, improving measurement reliability. The press-button controls with indicator lamps simplify operation and enhance safety.
4、Robust and Reliable: Designed with high-quality components, the system is built to be reliable for demanding test applications. The series complies with relevant ISO9001 quality management standards.

Application Scenarios

1、Power Utilities and Substations: Used for primary current injection testing of circuit breakers, protective relays, current transformers, and busbars during commissioning, maintenance, and troubleshooting.
2、Electrical Equipment Manufacturing: Employed by manufacturers for factory testing and quality control of high-current switchgear, transformers, and other apparatus to verify performance at rated currents.
3、Testing and Calibration Laboratories: Used in high-power laboratories for calibrating current-measuring devices, testing thermal characteristics of conductors, and performing research on high-current phenomena.
4、Industrial Plants: Utilized in heavy industries (e.g., steel, aluminum, petrochemical) for testing and maintaining large motors, generators, and high-current distribution systems.

FAQ

1、What is the primary purpose of the DDG Primary Current Injection Test Set?
The primary purpose is to generate a high, adjustable test current for performing primary current injection tests on electrical equipment. This test verifies the correct operation of protective devices, current transformers, and other equipment under high-current conditions, simulating real-world fault currents.
2、What are the typical operating cycles for this equipment?
The DDG series is designed for short-time or intermittent working systems. It is not typically rated for continuous 100% duty cycle. The specific duty cycle should be confirmed with the manufacturer, but standard practice is to allow for cooling periods after a high-current output.
3、How is the output current monitored?
The output current is monitored using the built-in dual ammeter system. The two ammeters allow for monitoring across a size range to ensure accurate measurement. An autotransformer provides fine adjustment of the current during the test.
